You can't.

No, seriously, you won't find a video card (especially an nVidia) that doesn't have a cross-licensing agreement with Microsoft for the use of certain patented codecs. Whatever you buy, there's gonna be a small amount of cash going to Microsoft. Sorry.

Have you considered being less indignant and working to encourage other people to be more aware of the security of their data?
